What is the output of a thermocouple?
What is the output of a thermocouple?
Show Hint
Thermocouples are active transducers, meaning they generate their own electrical signal (voltage) and do not require an external power source to operate.
This distinguishes them from passive sensors like RTDs and thermistors, which change resistance.

- A thermistor has a resistance of $10\text{ k}\Omega$ at $25^\circ\text{C}$ and $1\text{ k}\Omega$ at $100^\circ\text{C}$. The range of operation of is $0^\circ\text{C}$ to $150^\circ\text{C}$. The excitation voltage is $5\text{V}$ and a series resistance of $1\text{ k}\Omega$ is connected to the thermistor. The power dissipated in the thermistor is}
